... Ideal when building a house ...

Exactly what I was looking for: small, logical and does what it promises.
The displayed time stamp at the bottom is also very helpful.
The supplied USB stick is also nice but larger cards are also recognized.
Einzeiges drawback is that you have to the angle that the camera image covers first time looking for himself - as an aid: index and middle finger like a "V" apart stretch - this is the angle that it covers.
Alignment can be the thing at its best with a laser pointer ;-)

And do not forget - must remain free to read the back of batteries and replace USB stick - that makes places directly on the wall before unusable for longer stretches of time.

But all in all a great thing - if I will use it for the construction, I can watch at the grass grow but at present not yet estimate.
